Sensor Tower: Apple's App Store net revenue fell by around 5% in September, the steepest drop since 2015, as gaming revenue declined by 14%

Context & Ripple Effects
Sensor Tower's September numbers mark a sharp reversal from the App Store's boom years, when Apple's store grew 34.7% YoY in 2017 and US iPhone users' average annual app spend climbed from $33 in 2015 to $79 by 2018. The composition explains the severity: games have long dominated iOS monetization, accounting for 68% of total iOS App Store revenue as of 2019, so a 14% gaming drop pulls the whole store down.
The report lands mid-correction for mobile gaming broadly, and it gives Apple's critics fresh ammunition: a shrinking commission base strengthens the case regulators and developers have been making about the platform's cut.
First-order effects
- Gaming-focused developers take the immediate hit, since their category drove both the 14% decline and the bulk of App Store revenue historically.
- Apple's high-margin Services segment loses its fastest-compounding engine, turning App Store net revenue negative for the first time since at least 2015 by Sensor Tower's measure.
Second-order effects
- Apple faces mounting pressure to diversify App Store monetization beyond the 30% purchase commission — search advertising being the obvious lever — as pure transaction volume contracts.
- Rivals and developers watching the same Sensor Tower data will read the gaming slump as a market-wide demand problem rather than an Apple-specific one, reshaping user-acquisition budgets toward retention of existing spenders.
Third-order effects
- If post-pandemic pullback proves structural rather than seasonal, the decade-long assumption that App Store revenue compounds upward breaks — and a shrinking pie intensifies fights over the platform take rate, since every point of commission matters more when the base stops growing.
- Sustained declines would push Apple to lean harder on non-commission revenue streams (ads, subscriptions outside IAP), gradually changing what the App Store is as a business.
The trend: The mobile app economy is rotating from a decade of uninterrupted growth into its first sustained contraction, led by gaming — forcing platform owners to rebuild monetization around advertising and subscriptions rather than purchase commissions.
